The Go Direct CO₂ Gas Sensor measures gaseous carbon dioxide concentration levels, air temperature, and relative humidity.

The Electrode Amplifier is an ORP/mV/pH amplifier that accepts an electrode with a standard BNC connector. It amplifies a –450 mV to +1100 mV range to the 0 - 5 V range of our interfaces.

4 Channel Input For ECG/EMG Recording.

The four-wavelength Go Direct Colorimeter measures absorbance or transmittance of a liquid sample.

A rugged, general-purpose temperature sensor that students can use to monitor temperature.

The Go Direct O₂ Gas Sensor measures gaseous oxygen concentration levels and air temperature.

The Go Direct Gas Pressure Sensor measures the absolute pressure of a gas.

We offer different packages to meet your needs and budget for the elementary classroom.

Precisely records the number of drops of titrant added during a titration and then automatically converts it to volume.

The sound level sensor allows users to easily measure sound level in decibels (dB) in a variety of school settings. Simply connect and collect, as no background knowledge of sound-level weighting, response times, or the decibel scale is needed to use this sensor.

The Accu-CT split-core current transformer offers outstanding accuracy and one-handed operation.

We offer different packages to meet your needs and budget for the middle school classroom.

The Go Direct Voltage Probe combines a wide input voltage range and high precision, making it an excellent choice for investigations of both AC/DC circuits and electromagnetism.

The Go Direct EKG Sensor records electrical signals produced during heart or muscle contractions.

The Go Direct Rotary Motion Sensor measures angular motion.

The Go Direct Optical Dissolved Oxygen Probe makes it easy to measure dissolved oxygen concentration, water temperature, and atmospheric pressure.
